About Sleeve Bearings

Choose a sleeve bearing that matches your load and speed requirements and that's right for your environment.

Dry-Running Metal-Reinforced Plastic Sleeve Bearings

Combine slippery plastic with the strength of metal. The PTFE core is naturally slippery, so you’ll never have to add lubricant. These bearings also keep your workspace clean with no lubricant to drip or flake and attract dust. Compared to all-metal bearings, they are lighter.

With no moving parts, sleeve bearings are the simplest way to support the load of a rotating shaft while reducing friction. Also known as plain bearings.

PTFE with 17-4 PH Stainless Steel Shell—The highest load capacity of any sleeve bearing we offer. 17-4 PH stainless steel offers good corrosion resistance but is heavier than aluminum.

Mil. Spec. Ball Joint Rod Ends

Made of cadmium-plated steel, these rod ends generally handle higher loads than stainless steel, aluminum, and nylon rod ends. They provide moderate corrosion resistance. All have a PTFE liner that allows smooth ball rotation and eliminates the need for lubrication. Liner meets SAE AS81820.

Oversized Shank—Rod ends with an oversized shank have a shank that is one size larger than the ID to handle greater stress.

Multiple thread channels (also known as thread starts) create faster linear travel than lead screws with a single thread start. Operating with less backlash (play) than Metric Precision Acme Lead Screws and Nuts, these lead screws and nuts provide increased nut life and more reliable movement in automated systems. To ensure compatibility, select components that have the same thread size and number of thread starts.

Quick-Grip Flanged Hydraulic Bushings

Tighten just one set screw to clamp these bushings evenly around your shaft. The screw forces hydraulic fluid in between the double-walled sleeve, expanding the two walls against the shaft and the hub of your sprocket, pulley, or gear for a tight hold. Since you don’t have to tighten multiple screw clamps individually, these bushings are quick to adjust and more likely to stay aligned on your shaft. They’re also good for shock loads. A mounting flange prevents movement during tightening. Use a hex key to tighten.

Note: To avoid deforming the sleeve walls, make sure to fully tighten the screw.

17-4 PH Stainless Steel—17-4 PH stainless steel bushings have excellent corrosion resistance in most environments.

Corrosion-Resistant Fully Threaded Rod End Bolts

17-4 PH Stainless

Steel

Image of Attribute. Front orientation. Contains Annotated, MultipleImages. Corrosion-Resistant Fully Threaded Rod End Bolts.

These rod end bolts are good for wet and corrosive environments—for maximum mounting flexibility, cut the fully threaded shaft to whatever length you need. Also known as swing bolts and eyebolts, rod end bolts have no moving parts. They're designed to make pivoting or hinge movements in applications that don't need to compensate for misalignment.

17-4 PH Stainless Steel—17-4 PH stainless steel rod end bolts have the most tensile strength—a similar amount to high-strength alloy steel. They also won’t rust in humid, wet, and washdown environments. Even at high temperatures, they maintain their excellent strength and corrosion resistance, so they’re often used in automotive drive trains and heat exchangers. However, they’ll rust when exposed to salt water and chemicals.

ASTM A564—ASTM rod end bolts meet a standard for material.

Metric Ultra-Precision Lead Screws and Nuts

Operating with less backlash (play) than Metric Precision Acme Lead Screws and Nuts, these provide increased nut life and more reliable movement in automated systems. Also known as single-start and self-locking lead screws and nuts, they have a single thread that runs the length of the screw. The nut travels only when the screw turns, so your system won't unexpectedly move when the lead screw is at rest. To ensure compatibility, select components that have the same thread size, thread type, thread size, thread pitch, and number of thread starts.

Travel Distance per Turn—Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.

Fast-Travel Corrosion-Resistant Ball Screws and Nuts

Multiple thread channels (also known as thread starts) create faster linear travel than ball screws with a single thread start. Suitable for use in harsh environments, these ball screws and nuts are made of stainless steel. Internal ball bearings provide smooth low-friction travel in applications that require high speeds, accurate positioning, and repeatable movement. To ensure compatibility, select components that have the same thread size. Ball nuts are furnished with a tube to keep ball bearings in place. Do not remove the tube until you are ready to install the nuts onto the screws.
